“…As a consequence, it might lead to improved behavior in a variety of uses (Safaei et al 2019). Manna et al (2018) synthesized Zn(II)-Based MOF. This metal-organic framework was created via gradual diffusion of the ligand L and ZnSiF 6 at room temperature, resulting in block-shaped yellow crystals.…”

Metal-organic frameworks (MOFs) are currently popular porous materials with research and application value in various fields such as medicine and engineering. Aiming at the application of MOFs in photocatalysis, this paper mainly reviews the main synthesis methods of ZnMOFs and the latest research progress of ZnMOFs-based photocatalysts to degrade organic pollutants in water, such as organic dyes. This nanomaterial is being used to treat wastewater and has proven to be very efficient because of its exceptionally large surface area and porous nature. The results show that Zn-MOFs are capable of high degradation of the above pollutants and over 90% of degradation was observed in literatures. In addition, the reusability percentage was examined and studies showed that Zn-MOFs nanostructure has very good stability and can continue to degrade a high percentage of pollutants after several cycles. This review focuses on Zn-MOFs and their composites. First, the methods of synthesis and characterization of these compounds are given. Finally, the application of these composites in the process of photocatalytic degradation of dye pollutants such as MB, methyl orange (MO), crystal violet (CV), RhB, etc. is explained.

“…Powder X-ray diffraction analysis was carried out to investigate the crystallinity of the Zn-MOF in the bulk phase, where a slight right shift for the peaks of the experimental data was observed (Figure S3). The considerable shift in peaks may be due to the reallocation of the interpenetrated network after the removal of the guest molecules from the voids while drying. , However, crystallinity of the structure remained intact in bulk phase. Besides, the chemical stability of the Zn-MOF was also attempted by soaking the material in aqueous solution with different pH.…”

This report deals with the fabrication and utilization of a novel 2D zinc-based metal−organic framework (MOF) {[Zn(PA 2− )(4,4′-bpy)]-(H 2 O)} n (where PA = pamoic acid and 4,4′-bpy = 4,4′-bipyridine). The Zn-MOF has been synthesized via a solvothermal method and emanates green fluorescence. As Cr(VI) is a fatal and carcinogenic ion, it is extremely important to discern and remove it from nature. The bright green fluorescence of Zn-MOF can be quenched upon interaction with a Cr 2 O 7 2− ion, which implies the MOF's applicability as a Cr(VI) detector through turn-off fluorescence signaling. On the contrary, among various strategies to remove Cr(VI), the photocatalytic reduction of Cr(VI) to Cr(III) is acknowledged as the most effective one. Delightfully, apart from being a Cr(VI) sensor, this same Zn-MOF can be further recruited as a photocatalyst to convert Cr(VI) to Cr(III). The catalytic reduction is triggered by natural sunlight, acidic pH, and a hole scavenger. In addition, good stability and reusability of the Zn-MOF satisfies the quest for a potential photocatalyst for conversion of Cr(VI) to Cr(III). The limit of detection for fluorometric recognition of Cr(VI) was found to be 4.12 μM, and almost a complete reduction of toxic Cr(VI) ion was achieved.

“…Notably, the measured pore volume of UTSA-220 is 0.35 cm 3 / g based on 77 K N 2 isotherm (at P/P 0 = 0.85), which is consistent with the theoretical value of 0.33 cm 3 /g from crystal structure, implying the well retention of its porosity. In contrast, the zinc analogue of UTSA-220 shows far lower measured pore volume, 50 which might be attributed to its high humidity sensitivity.…”

Separating acetylene from light hydrocarbon mixtures like ethylene is a very important process for downstream industrial applications. Herein, we report a new MOF [CuL 2 (SiF 6 )] (UTSA-220, L = (1E,2E)-1,2-bis(pyridin-4ylmethylene)hydrazine) with dual functionalities featuring optimal pore size with strong binding sites for acetylene. UTSA-220 exhibits apparently higher uptake capacity for C 2 H 2 than those for other light hydrocarbons. The potential of this material for trace C 2 H 2 removal from C 2 H 4 has also been demonstrated by a dynamic breakthrough experiment performed with C 2 H 2 / C 2 H 4 (1/99 v/v) under simulated industrial conditions. According to the dispersion-corrected density functional theory (DFT-D) simulation, SiF 6 2− and azine moieties serve as preferential binding sites for C 2 H 2 , indicating the feasibility of the dual functionalities incorporated in UTSA-220 for adsorbent-based C 2 H 2 separations.
